[0003] In existing massage devices, a leg support plate or calf extension module that can be pulled forward is commonly included. These movable components are connected to the main frame via guide rails, slides, or swing arms, enabling large-stroke extension and folding under electric or manual drive. However, these movable components come into direct contact with the main body during extension or folding, which can easily interfere with the flexible cover such as cloth or leather covering the main body. Utility Model Content

[0004] This utility model provides a massage device that aims to solve the problem that the leg support part of the massage device easily interferes with the cloth cover when pulled out from the base.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A massage device includes a base and a backrest disposed on the base. The base is provided with a guide assembly, which includes an upwardly protruding arc-shaped slide rod. It also includes a leg support portion, which is movably connected to the arc-shaped slide rod, such that the leg support portion moves along the arc-shaped slide rod and has a first position in a retracted state and a second position in a working state.

[0007] When the leg support moves between the first position and the second position, the distance between the leg support and the backrest gradually increases and then decreases to reduce the contact between the leg support and the backrest during the movement.

[0008] Furthermore, the guide component is hinged to the base on the side near the first position, and a lifting component is connected to the side of the guide component near the second position. The lifting component drives the guide component to rotate hingedly, thereby moving the leg support between the second position and the third position.

[0009] When the leg support is in the third position, the seat surface of the leg support and the seat surface of the backrest are on the same plane or tend to be on the same plane.

[0010] Furthermore, the base is fixed with a first arc-shaped slide rail, and the side of the guide component near the second position is slidably disposed in the first arc-shaped slide rail. The end of the guide component near the second position is respectively provided with a first roller, and the two first rollers are movably connected in the first arc-shaped slide rail.

[0011] Furthermore, the lifting assembly includes a first push rod hinged to the base, the output end of the first push rod being connected to a lifting bracket, and the lifting bracket being connected to the guide assembly and the first guide wheel; when the leg support is between the first position and the second position, the first guide wheel abuts against the bottom of the leg support.

[0012] Furthermore, a sliding member is movably disposed on the arc-shaped sliding rod, and a mating part is provided on the leg support part. The sliding member is connected to the mating part, so that the leg support part is slidably connected to the arc-shaped sliding rod.

[0013] Furthermore, the base is provided with a second arc-shaped slide rail, and the backrest is movably connected to the second arc-shaped slide rail, so that the backrest rotates in a circle around the geometric center of the second arc-shaped slide rail.

[0014] Furthermore, the base is also provided with a seat cushion, and the center of the second arc-shaped slide rail is located on the top edge of the seat cushion near the backrest, so that the backrest maintains a stable distance from the top edge of the seat cushion during rotation.

[0015] Furthermore, it also includes a steering assembly, which includes a steering member and a transmission rod that are hinged to each other. The end of the transmission rod away from the steering member is hinged to the backrest, the middle part of the steering member is hinged to the base, and the end of the steering member away from the transmission rod is hinged to a second push rod, which is mounted on the base.

[0016] Furthermore, the backrest includes a backrest support, and a connecting component is provided at the bottom of one end of the backrest support. The connecting component is slidably connected to the second arc-shaped slide rail.

[0017] Furthermore, the backrest is equipped with a massage mechanism, and the backrest support is equipped with a rack for transmission adaptation with the massage mechanism, and the massage mechanism can reciprocate along the rack.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model discloses a massage device, including a base and a backrest rotatably connected to the base. The base is provided with a guide assembly, which includes an upwardly protruding arc-shaped slide rod. A leg support is slidably connected to the arc-shaped slide rod, and the leg support can slide along the arc-shaped slide rod between a first position and a second position, achieving synchronous movement in both horizontal and vertical directions. In the first position, the leg support is retracted above the base, saving space occupied by the massage device when the user does not need leg support. In the second position, the leg support is pulled out from the base, better conforming to the user's leg extension posture and providing comfortable and appropriate support for the legs. Simultaneously, the design of the arc-shaped slide rod causes the height of the leg support to rise and then fall during the pulling-out process, effectively reducing interference between the leg support and the flexible cover such as the fabric covering the base or backrest during movement, thus improving the convenience and comfort of using the massage device.

[0020] 2. The massage device proposed in this utility model includes a seat cushion on the top of the base. One side of the guide component is hinged to the base, and the other side is connected to a lifting component. In the working state, the leg support is pulled out to the second position. Then, the lifting component drives the rotation of the guide component, thereby moving the leg support from the second position downward to the third position. At this time, the leg support and the seat cushion are horizontal, allowing the user to naturally place their legs so that they are horizontal with the body parts sitting on the seat cushion, thereby further improving the comfort and relaxation during use.

[0021] 3. The massage device proposed in this utility model also includes a first arc-shaped slide rail. The guide component is provided with two first rollers movably connected to the first arc-shaped slide rail on the side near the second position. The hinge of the two first rollers and the guide component forms a triangular structure to enhance the overall structural stability of the guide component. When the height of the leg support is adjusted, the force can be effectively dispersed, the shaking caused by uneven force can be reduced, and the smoothness of the movement of the leg support can be ensured.

[0022] 4. The massage device proposed in this utility model has a base with a second arc-shaped slide rail. The backrest is slidably connected to the second arc-shaped slide rail. The center of the second arc-shaped slide rail is located on the top edge of the seat cushion near the backrest. This allows the backrest to rotate around the geometric center of the second arc-shaped slide rail and always maintain the same distance from the seat cushion. Maintaining the same distance between the backrest and the seat cushion effectively avoids discomfort that may be caused by changes in distance, and further improves the overall comfort and practicality of the massage device.

[0023] 5. The massage device proposed in this utility model also includes a steering assembly. A second push rod and a backrest are respectively hinged to both ends of the steering assembly. The design of the steering assembly effectively reduces the space occupied. It also includes side panels, a front panel, and a baffle that enclose an installation space. The lifting assembly and steering assembly are concealed within this installation space, reducing the risk of external damage and making the device more aesthetically pleasing, safe, and reliable.

[0024] 6. The massage device proposed in this utility model also includes a massage mechanism. The backrest includes a backrest support with a rack. The massage mechanism moves back and forth on the backrest support by meshing with the rack, thereby meeting the user's massage needs. Attached Figure Description

Detailed Implementation

[0046] The following is combined Figure 1-19 This utility model will be described in detail.

[0047] A massage device, such as Figure 1 and Figure 2 As shown, the device includes a base 10 and a backrest 30 disposed on the base 10. The base 10 is provided with a guide assembly 40, which includes an upwardly protruding arc-shaped slide rod 401. It also includes a leg support 50, which is movably connected to the arc-shaped slide rod 401, so that the leg support 50 moves along the arc-shaped slide rod 401 and has a first position in a retracted state and a second position in a working state.

[0048] When the leg support 50 moves between the first position and the second position, the distance between the leg support 50 and the backrest 30 gradually increases and then decreases to reduce the contact between the leg support 50 and the backrest 30 during the movement.

[0049] Specifically, such as Figure 4 and Figure 5 As shown, in the first position, the leg support 50 moves to the end of the curved slide bar 401. At this time, the leg support 50 is in a retracted state, stored above the base 10, allowing the massage device to occupy less space when the user does not need leg support. In the first position, the distance between the leg support 50 and the backrest 30 is H1. When the leg support 50 is pulled outward to move to the second position, as... Figure 6 As shown, the leg support 50 slides smoothly along the curved slide bar 401, and the distance between it and the backrest 30 gradually increases until the leg support 50 moves to the top of the protrusion of the curved slide bar 401, as shown in the figure. At this time, the distance between the two is H2. Continuing to pull the leg support 50 towards the second position, the distance between the leg support 50 and the backrest 30 gradually decreases during the movement until the second position is reached, as shown in the figure. Figure 7 As shown, the distance between the leg support 50 and the backrest 30 is H3. The leg support 50 is located at the other end of the curved slide bar 401, providing support for the legs. The design of the curved slide bar 401 allows the height of the leg support to change accordingly as it moves horizontally, effectively reducing interference between the leg support 50 and the flexible cover such as the cloth or leather cover of the backrest 30 during movement, thus improving the convenience and comfort of using the massage device.

[0050] In other embodiments, the second position can be any position where the leg support 50 is away from the first position. That is, the setting of the first and second positions is not limited to the end of the arc-shaped slide bar 401. It is only necessary to ensure that the leg support 50 is adjusted in both horizontal and vertical position during movement to avoid contact with the backrest 30.

[0051] like Figure 15 As shown, the guide assembly 40 is hinged to the base 10 on the side near the first position, and a lifting assembly 60 is connected to the side of the guide assembly 40 near the second position. The lifting assembly 60 rotates the hinge of the guide assembly 40, thereby moving the leg support 50 between the second and third positions. When the leg support 50 is in the third position, the seat surface of the leg support 50 and the seat surface of the backrest 30 are on the same horizontal plane or approach the same horizontal plane. In use, the leg support 50 is first moved to the second position, and then the lifting assembly 60 moves the leg support 50 downward to the third position, as shown. Figure 8 As shown, the user can place their legs naturally at this time, which enhances the comfort and relaxation when using the extended leg.

[0052] like Figure 16 As shown, the base 10 is fixed with a first arc-shaped slide rail 101, and the side of the arc-shaped slide rod 401 near the second position is slidably disposed within the first arc-shaped slide rail 101. The first arc-shaped slide rail 101 provides a stable path for the rotation of the guide assembly 40, ensuring the stability and accuracy of the leg support 50 during movement, thereby reducing discomfort to the user that may be caused by unstable movement. A first roller 404 is respectively provided at one end of the guide assembly 40 near the second position. The two first rollers 404 are movably connected within the first arc-shaped slide rail 101, and the hinge points of the two first rollers 404 and the guide assembly 40 form a triangular structure. This triangular structure design enhances the overall structural stability of the guide assembly 40. When the leg support 50 is adjusted in the height direction, it can effectively disperse the force, reduce the swaying caused by uneven force, and ensure the smooth movement of the leg support 50. Specifically, the guide assembly 40 also includes an auxiliary rod 402, the two ends of which are fixed to the two ends of the arc-shaped slide rod 401 via connectors 403. A first roller 404 is respectively provided at the end of the auxiliary rod 402 and the arc-shaped slide rod 401 near the second position. In other embodiments, the guide assembly 40 may also be a triangular structure consisting only of the arc-shaped slide rod 401, the auxiliary rod 402, and the connector 403 connected end-to-end. One end of the arc-shaped slide rod and the auxiliary rod is hinged to the base 10, and the other end of the arc-shaped slide rod and the auxiliary rod near the connector 403 is respectively provided with a first roller 404.

[0053] The lifting assembly 60 includes a first push rod 601 hinged to the base 10. The output end of the first push rod 601 is connected to a lifting bracket 602, which is connected to the guide assembly 40 and a first guide wheel 603. When the leg support 50 is between the first and third positions, the first guide wheel 603 abuts against the bottom of the leg support 50 to reduce friction between the leg support 50 and the base 10. Furthermore, the lifting assembly 60 also includes a sensing device (omitted in the figure) for detecting the position of the leg support 50. When the sensing device detects that the leg support 50 is in the second position, it sends a feedback signal. The first push rod 601 receives this feedback signal and operates to automatically lower the leg support 50. After use, the user manually controls the first push rod 601 via a button to push the leg support 50 back to the second position, and finally pushes the leg support 50 back to the first position along the arc-shaped guide rod. The button can be a control component set on the first push rod 601, or it can be a control component set independently of the first push rod 601 and connected to the first push rod 601 by signal.

[0054] A sliding member 405 is movably mounted on the arc-shaped slide rod 401. The leg support 50 has a mating part 5021, and the sliding member 405 is connected to the mating part 5021, so that the leg connecting frame 502 is slidably connected to the arc-shaped slide rod 401. Specifically, an arc-shaped slide rod 401 is provided on both sides of the base 10, and a sliding member 405 is movably mounted on each arc-shaped slide rod 401. The leg connecting frame 502 has two mating parts 5021 that correspond one-to-one with the two sliding members 405. Each mating part 5021 forms a receiving space adapted to the sliding member 405, and the sliding member 405 is fixed in the receiving space of the mating part 5021 by screws or other parts. The protective plate 505 also has an operating part 5051 to facilitate the movement of the leg support 50 during use.

[0055] like Figure 17 As shown, the second end of the leg support 501 is bent towards the ground and is provided with a second guide wheel 503. A support plate 504 for supporting the user's legs and a protective plate 505 spliced ​​to the support plate 504 are also fixed on the leg support 501. The support plate 504 and the protective plate 505 are fixed to the leg support 501 by screws and other parts.

[0056] like Figure 9 and Figure 10As shown, the base 10 is provided with a second arc-shaped slide rail 102, and the backrest 30 is movably connected within the second arc-shaped slide rail 102, allowing the backrest 30 to rotate in a circle around the geometric center of the second arc-shaped slide rail 102. Furthermore, the base 10 also provides a seat cushion 20. When the leg support 50 is in the third position, the seat surface of the seat cushion 20, the seat surface of the leg support 50, and the seat surface of the backrest 30 are on the same horizontal plane or approach the same horizontal plane, so that the leg support 50 will not interfere with the base 20 when it is pulled out. The center of the second arc-shaped slide rail 102 is located on the top edge of the seat cushion 20 near the backrest 30, so that the backrest 30 maintains a stable distance from the top edge of the seat cushion 20 during rotation. Figure 11 and Figure 12 As shown, the spacing is LI, effectively avoiding discomfort that may be caused by changes in spacing, further improving the overall comfort and practicality of the massage device. Existing technologies often use direct hinges, exposing transmission components such as push rods, which affects the appearance and causes non-equidistant rotation and uneven force distribution. In contrast, in this embodiment, the backrest 30 maintains a certain distance from the seat cushion 20 during rotation, and transmission components such as the second arc-shaped slide rail 102 can be accommodated under the backrest 30, reducing the overall space occupied by the device and making it safer and more aesthetically pleasing.

[0057] In this embodiment, as Figure 18 As shown, the backrest also includes a steering assembly, which comprises a steering component 701 and a transmission rod 702 hinged together. The end of the transmission rod 702 away from the steering component 701 is hinged to the backrest 30. The middle part of the steering component 701 is hinged to the base 10. A second push rod 703 is hinged to the end of the steering component 701 away from the transmission rod 702, and the second push rod 703 is mounted on the base 10. Specifically, the steering component 701 is hinged to two transmission rods 702, which are respectively hinged to both sides of the backrest 30. The backrest 30 includes a backrest support 301. A connecting component 302 is provided at the bottom of one end of the backrest support 301. The connecting component 302 has several second rollers 3023 facing the second arc-shaped slide rail 102, and each second roller 3023 is movable within the second arc-shaped slide rail 102. Specifically, a set of connecting components 302 is provided on each side of the backrest 30, and the connecting components 302 are slidably connected to the second arc-shaped slide rail 102. Each connecting component 302 includes two vertical rods 3021 perpendicular to the backrest support 301. The ends of the two vertical rods 3021 away from the backrest support 301 are connected to a horizontal rod 3022. The horizontal rod 3022 is provided with two second rollers 3023, so that the connecting component 302 is slidably connected to the second arc-shaped slide rail 102. A connecting part is provided on one of the vertical rods 3021 near the transmission rod 702, and the transmission rod 702 is hinged to the connecting part.

[0058] Compared to existing conventional solutions where the push rod directly pushes the backrest 30, which exposes the push rod when the backrest 30 is pushed up, this patent incorporates a steering component 701 inside the base 10. This avoids the hinge being exposed externally, which could lead to accidental activation by the user. Furthermore, the steering component 701 allows the second push rod 703 to be positioned below the backrest 30, saving space. Additionally, the lever effect of the transmission rod 702 shortens the stroke required to push up the backrest 30, and the steering component and connecting component 302 remain hidden inside the base 10 throughout the process of pushing up the backrest 30.

[0059] like Figure 19 As shown, it also includes a massage mechanism 80, and the backrest support 301 is provided with a rack 303 for transmission adaptation with the massage mechanism 80. The massage mechanism 80 can reciprocate along the rack 303, such as... Figure 13 and Figure 14 As shown, this design is intended to meet the user's massage needs. The side of the backrest support 301 facing the user is covered with a back panel 304, enhancing user comfort. Figure 3 As shown, the massage device also includes two side plates 901 located on the left and right sides of the base 10, and a front plate and a baffle 902 connected to the two. The two baffles 902, the front plate and the side plates 901 are connected end to end and enclose to form an installation space. The lifting component 60 and the steering component are hidden in the installation space, which can reduce the risk of damage to the lifting component 60 and the steering component, and make the appearance of the entire massage device more neat and beautiful.

[0060] The massage device provided by this utility model is used as follows:

[0061] In the folded state, the leg support 50 is folded above the base 10. At this time, the leg support 50 is in the first position, and the distance between the leg support 50 and the backrest 30 is H1.

[0062] In use, the leg support 50 moves along the curved slide bar 401, gradually increasing the distance between the leg support 50 and the backrest 30 to H2, and then gradually decreasing to H3. At this time, the leg support 50 is in the second position. The sensor detects the information of the leg support 50 in the second position and controls the first push rod 601 to retract. The lifting bracket 602 then descends and drives the guide assembly 40 to rotate around its pivot point. The leg support 50 moves from the second position to the third position, so that the seat surface of the leg support 50 and the seat surface of the cushion are on the same horizontal plane or close to the same horizontal plane.

[0063] Adjust the rotation angle of the backrest 30. Control the extension of the second push rod 703, which pushes the steering component 701 to rotate. The transmission component is then forced to move the connecting assembly 302 within the second arc-shaped slide rail 102 until the backrest 30 rotates around the seat cushion 20 to a suitable angle, at which point the second push rod 703 stops changing length. Finally, control the massage mechanism 80 to operate to achieve massage.

[0064] The massage is over. Control the second push rod 703 to retract the backrest 30, then control the first push rod 601 to push the leg support 50 back to the second position. Finally, manually push the leg support 50 back to the first position to complete the storage.

[0065] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
